CPU Lock FreeASUS Motherboards now offer the CPU Lock Free feature, which allows you to adjust CPU multiplier to 14x. The reduction of multiplier value provides more flexibility for increasing external FSB frequency to raise memory bus bandwidth. Enjoy better performance at the same CPU operation speed and improve your system without pushing the CPU to the limit.

PCI Express ArchitecturePCI Express is the latest I/O interconnect technology that will replace the existing PCI interface. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming.

Dual-Channel DDR400Dual-channel DDR technology doubles the bandwidth of your system memory and hence boost the system performance to out perform any memory existing solutions in the market. System bottlenecks are eliminated with balanced architecture and peak bandwidths up to 6.4GB/s.

ADI SoundMAX High Definition AudioThe onboard 6-channel High Definition audio CODEC enables high-quality ADI AD1986A audio CODEC, which automatically detects and identifies what types of peripherals are plugged into the audio I/O jacks and notifies users of inappropriate connection, meaning there will be no more confusion of Line-in, Line-out and Mic jacks.

Serial ATASerial ATA is the next generation ATA specification that provides scalable performance for today and tomorrow. With up to 150MB/s data transfer rate, Serial ATA is faster than current Parallel ATA.

ASUS CrashFree BIOS2The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

C.P.R.(CPU Parameter Recall)When the system hangs due to overclocking failure, there is no need to open the case to clear CMOS data. Just simply restart the system, the BIOS would show the previous setting and then users can amend the CPU setting again.

Compliance with the RoHS Directive The motherboard and its packaging comply with the European Union's Restriction on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision of creating environment-friendly and recyclable products and packaging to safeguard consumers' health while minimizing the impact on the environment.
